Scaling relations for earthquake source parameters and magnitudes
A data set of 41 moderate and large earthquakes has been used to derive scaling rules for kinematic fault parameters. If effective stress and static stress drop are equal, then fault rise time, τ,Expand

Robert J. Geller calls on Japan to stop using flawed methods for long-term forecasts and to scrap its system for trying to predict the 'Tokai earthquake'.
Earthquake prediction: a critical review
SUMMARY Earthquake prediction research has been conducted for over 100 years with no obvious successes. Claims of breakthroughs have failed to withstand scrutiny. Extensive searches have failed toExpand
Four similar earthquakes in central California
We study four ML - 2.7 earthquakes on the San Andreas Fault in Central California. The first two events occurred within five minutes of each other in November 1978; the two events in January 1979Expand
Did a submarine landslide contribute to the 2011 Tohoku tsunami
Many studies have modeled the Tohoku tsunami of March 11, 2011 as being due entirely to slip on an earthquake fault, but the following discrepancies suggest that further research is warranted. (1)Expand
Magnitudes of great shallow earthquakes from 1904 to 1952
The “revised magnitudes”, M, converted from Gutenberg's unified magnitude, m, and listed by Richter (1958) and Duda (1965) are systematically higher than the magnitudes listed by Gutenberg andExpand
Earthquakes Cannot Be Predicted
Can the time, location, and magnitude of future earthquakes be predicted reliably and accurately? In their Perspective, Geller et al.'s answer is “no.” Citing recent results from the physics ofExpand
Optimally accurate second-order time-domain finite difference scheme for the elastic equation of motion: one-dimensional case
SUMMARY We previously derived a general criterion for optimally accurate numerical operators for the calculation of synthetic seismograms in the frequency domain (Geller & Takeuchi 1995). We thenExpand
Computation of synthetic seismograms and their partial derivatives for heterogeneous media with arbitrary natural boundary conditions using the Direct Solution Method
SUMMARY A new method is presented for calculating synthetic seismograms and their partial derivatives for laterally and vertically heterogeneous media with arbitrary natural boundary conditions.Expand
Why earthquake hazard maps often fail and what to do about it
Abstract The 2011 Tohoku earthquake is another striking example – after the 2008 Wenchuan and 2010 Haiti earthquakes – of highly destructive earthquakes that occurred in areas predicted by earthquakeExpand
